CLI FrameworkThe Next.js for CLI tools

Build production-grade command-line tools with zero boilerplate. One command, one function.

🚀

Zero Config

Auto-discover commands from your filesystem. Convention over configuration means you focus on writing business logic, not wiring up infrastructure.

🎨

Rich terminal UI out of the box — colored output, tables, spinners, progress bars, and interactive prompts. No extra libraries needed.

🔧

Full type inference for options, commands, and context. Write your CLI with the same confidence you get from your application code.

🧩

Extend your CLI with a first-class plugin architecture. Add commands, hooks, and middleware from npm packages or local files.

📋

Automatic bash, zsh, and fish completion for commands, subcommands, and options. One line to install.

🧪

Built-in test harness captures stdout/stderr and exit codes. Write integration tests for your CLI as easily as unit tests.
